Meaning
Two hands caught mid-clap, often with small motion lines. It means applause: congratulations, praise for a job well done, or appreciation for a great performance or idea.
It fits graduation posts, work milestones and anyone who deserves recognition: βYou ran your first marathon? Incredible ππβ There is also a sarcastic use, slow clapping for something foolish, and a style of emphasis where π goes π between π words, which reads as forceful or preachy. In sincere praise, one or two claps are plenty.
